Hello, thank you all for the replies. The two replies that I received seem to have different solutions. My 1099B does not have "date acquired" and "cost basis" (it says "--", so these two fields are blank?), and there is a description says "Box 5 with Code X" (unknown period). The reply from "rjs" says to input the acquired date and cost per my own records to column b (date acquired) and column e (cost), and leave column f and g blank (since it is not adjustment, the broker just didn't provide the info) on form 8949. The reply from "fanfare" says to put code "B" on column f and "0" on column g. Please clarify which way that I should do? Thanks much.
